Refer to the following topics to help you diagnose and fix problems while using your G7500 and
Studio X series system.
Audio Issues
If you're having issues with audio or audio peripherals, refer to the following topics for guidance.
On a G7500 with a Studio E70 Camera and 3.5 mm Audio DSP Echoes Are
Heard on the Far End
In a call using a G7500 system with a Studio E70 camera and connected audio DSP, the far end
reports hearing echoes.
If you enable USB audio on a system with a connected 3.5 mm DSP audio system both the Studio
E70 and the DSP sends audio to the far-end resulting in echoes.
The Studio E70 microphones are for sound source location only and shouldn’t be used to pick up and
send room audio.
Make sure that the USB Audio setting is disabled in the system web interface.
1. In the system web interface, go to Audio/Video > Audio > General Audio Settings.
2. Verify that the Enable USB Audio check box is cleared.
